Abstract

A rectifier (5) of an alternator (1) includes positive and negative rectifier elements (53, 53). Each rectifier element has a lead wire (531, 541) connected thereto, and a vicinity of a portion connecting the lead wire to the element is sealed with a material such as resin or rubber, forming a sealing portion (61). To protect the sealing portion (61) against harmful components contained in cooling air blown to the rectifier, a conically shaped terminal (57) connected to the lead wire (531, 541) is disposed to face and cover the sealing portion (61). The terminal (57) has a sufficiently large surface area for dissipating heat generated in a process of connecting the lead wire (531, 541) to the terminal (57) by welding.
